UNITED STATES FRITZ DAI-ILIN, OF WEST MOSHANNON, 'PENNSYLVANIA.

CAN OPENER.

Application filed May 22,

To all whom it may concern: 7

Be it known that I, F rrz DAHLIN, a citizen of the United States, residing at West Moshannon, in the county of Clea-rfield and State of, Pennsylvania, have invented new and useful Improvements in Can Openers, of which the following is a specification.

This invention aims to provide a can opener which can be operated with the expenditure of a minimum amount of effort and designed to eliminate all possibility of the user from being injured incident to the slipping of the knife blade from the can as frequently occurs with other openers with which I am familiar.

Another object of the invention resides in the provision of a device of the above mentioned character designed to rigidly support the can While the latter is being opened, and including means for this purpose which is susceptible of adjustment to accommodate itself to cans of different size.

A further object of the invention resides in the provision of a can opener including a can supporting frame and a rotatable cutter blade, the latter being capable of adjustment so as to be properly positioned with respect to cans of different size.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a view in elevation showing the invention supporting a can for the purpose specified.

Figure 2 is a sectional view taken on line 2---2 of Figure 1.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is an enlarged fragmentary sectional view of the cutting blade and its supporting means.

Figure 5 is a sectional view taken on line 5-5 of Figure 3.

Referring to the drawings in detail, 10 indicates a base from which rises a plur'ality! of standards 11, the latter being suitably connected together by spaced annuli 12, these parts unitedly defining a frame-like 1922. Serial No. 562,897.

structure which is adapted to receive and support the can 13 while the top of thelator is being severed. Supported by the standards 11 are suitable bearings 14 for pinions 15, the latter being threadedly associated with the clamping elements 16, there being one of these elements for each pinion. The clamping elements are horizontally disposed,

and the corresponding inner extremities: of

said elements support arcuate-shaped members 17 to accommodate themselves to the curvature of the can '13. The clamping elements 16 are susceptible of movement toward and away fro-m each other, or in other words moved radially to engage cans of different diameters, and for the purpose of simultaneously adjusting said clamping elements, I provide a ring gear 1.8, the-teeth of which mesh with the pinions 15. A crank handle 19 is journaled upon one of the standards 11 and supports a pinion 20 associated with the ring gear to turn the latter incident to the rotation of the said handle. Manifestly, when the handle is turned in one direction, the clamping elements 16 are moved inwardly in unison to effectively en gage the can supported upon the base 10, and when rotated in an opposite direction, causes the clamping elements to move outwardly or,

the latter being carried by a handle 26, as-

sociated with the cover for rotating the pinion. Arranged transversely of the ring gear is a cross piece 27 which is grooved as at 28 to slidably receive a block 29, the block having a threaded bore 30 which receives a threaded adjusting element 3l,'one end of which is provided with a knob or the like 32. Carried by the opposite end of this adjustable element is a cutter blade 83 which is associated with the element by means of suitable fastening elements 34 in a manner to permit the cutting blade to be removed therefrom when the occasion requires. The cutting blade may be of any suitable size or configuration without departing from the spirit of the invention. By reason of this construction, it is manifest that the adjusting element with which the blade is asso ciated, can be adjusted vertically to position the blade with respect to the top of the can to be severed, in order that the cutting blade may properly penetrate the can, and that the block 28 slidable in the cross piece 27 allows the cutting blade to be moved across the top of the can to be positioned adjacent one edge thereof, irrespective of the size or diameter of the can.

While it is believed that from the fore going description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim is A can opener comprising a frame like structure, a hinged cover for said frame like structure, a ring gear supported by the cover in cross section, a block arranged in said channel like portion for movement longitudinally of the cross bar, a threaded element passing through said block and arranged verticallyon said cover and adapted to be adjusted toward and away from the can, and acutting blade carried by the lower end of said, adjusting element and adapted to be forced through the top of the can and removing the latter as said gear is rotated.

In testimony whereof I aflix my signature.

FRITZ DAHLIN.
